Innovative Techniques for the Production of Low Cost 2D Laser Diode Arrays
Abstract
This program consists of four phases which will demonstrate reduced manufacturing cost and improved device performance of a MBE laser diode arrays. The four phases listed below will result in milestones in processing, packaging, and testing along with delivery of the specified number of 5-bar laser arrays. (1) Concept phase: Conceptual design and organization of this phase II program. NSI will utilize the current side cooled strained relief package to manufacture 5-bar laser diode arrays for base line evaluation. (Deliverables: 3 5-bar arrays). (2) Backplane phase: Development of a copper backplane cooling technology that incorporates CVD diamond submounts. This phase will also include the completion of room temperature photoluminescence development. (Deliverables: 5 5-bar arrays.) (3) Diamond Backplane Phase: Develop a CVD diamond backplane cooling scheme that will utilize smaller CVD submounts. The reduction in submount size is to decrease the thermal resistance from the laser bar to the backplane. (Deliverables: 5 5-bar arrays.) (5) Liquid Cooled Submount phase: An innovative liquid cooled package will be developed. The CVD diamond submounts will be hermitically sealed, electrically isolated and liquid cooled. (Deliverables: 5 5-bar arrays.)
